Facial spider veins can only be treated with certain types of lasers, and results are not always guaranteed.
However, researchers at the Boston University School of Medicine have concluded that the 940nm wavelength laser is the best option for treating all types of facial spider veins. Findings of the most recent study were published in the Lasers in Surgery and Medicine publication.
The study compared different lasers for treating open blood vessels on the outer layer of skin that are commonly caused by sun damage and the natural aging process. These types of veins can be caused by a number of skin problems including rosacea and acne, but may also be the result of genetic problems or a reaction from oral or topical corticosteroids. Currently, there are several different types of vein treatments available.
The 940nm wavelength laser has been proven to be effective for treating facial spider veins, and posed little side effects including slight pain, crusting, swelling and blistering. Researchers report that the pain associated with the 940nm wavelength laser was significantly less than the pain associated with 532nm and other wavelengths of lasers.
According to the author of the study Emily Tierney, MD, an assistant professor of dermatology at BUSM, "The 940nm diode laser was found to have greater efficacy for deeper blood vessels based upon its superior penetration of the dermis with a longer wavelength. In addition, the 940nm wavelength corresponds with a lesser absorption peak of oxyhemoglobin than that for 532 nm, resulting in slower and more uniform heating of the vessel.” (Source: MedicalNewsToday)
This wavelength of laser also poses fewer side effects such as scarring and post-inflammatory changes to the skin that are commonly associated with conventional lasers. Facial spider vein treatments are currently available at dermatology centers and some cosmetic surgery offices around the United States. This treatment must be performed by a licensed and/or certified medical professional.
